E.HEUSCH.. I APPARATUS FOR THE MANUFACTURE OF NEEDLES- APPLICATION HLIED APR. 25. I913 Patented Mar. 19, 191&

yaw roe I r A ro/iwsr To all whom .z'tmayconcern 7 subject of. the Emperor10f;Germany resich ing at-ijParis, SlRue- Michel-Bizot, 1n--the 7 more economic on account of the mechanical Be it known that :I, 'EDOUARD Henson, a

Republic of- France, manufacturer, have invented certain new and useful 'I-mprove-' 'ments 1n Apparatus. for the'Manufaeture of Needles, of which the following .is' a speci 'fication.

' This invention relates to improvements in the mechanical. manufacture of needlesyfor the. purpose of renderlng such manufacture execution of certain Ifinishing operations hitherto made by hand.

- Figure 1 shows diagrammatically a part of the process of the present invention; Fig. 2 shows a blank produced by the new' process;

Fig. 3 is a vertical section through a:-a: of Fig.5 and shows male and female dies on which .lies the needle blank connected by a fin. I

Fig.4 is a plan of the male die. Fig. 5 is a plan of the female die.

I The male die or punch is H shaped, its

transverse part having a width which corresponds to the interval or space between the needle heads. and the interval between its parallel members corresponding to the width of the heads. The female die has an opening so shaped as to correspond to that of the male die; it. possesses grooves on its upper face in order to receive the needle heads.

a, a designate the two matrices 1n the shape of vertical plates arranged in alinement with a space in between; in the top of each plate there is provided a recess a adapted to serve as a seat for the two needles connected head tohead as shown in Fig. 2, the adjacent ends a of the two plates a, a have a section which is rounded to conform with the shape of the head of the needles.

posed faces there are provided slots the cheeks b of which are adapted to slide against the lateral faces of the plates a,

while the central part or core 6 is adapted to slide-against the rounded surfaces of said plates. One of. the pairs of needles having been placed on the matrices a a and their fins 4 beingin the position shown in dotted lines in Fig. 5, the punch when moving downward will cause the fin to separate from the two needles and to slide downward along the matrices, leaving upon the latenemas F .jeaE- 4 ivseeeeae;m* amass.

*der perforating dies which perforate the eyes 5. Afterward the needles are thrown out of the machine, thev work of which has now been done. I I

The needles are then taken up by women operators who thread the needles on a string,

tion.

According to my invention, for operations by hand which follow the perforation of the eyes there are substituted different mechanical operations, while the stampingroperation must be so conducted as to produce between the heads a long bur, that is to say so as to give a result exactly the inverse of the one sought after by the method of manufacture now in use.

The invention consists in advancing the needles coupled together by their burs 4, after the perforation of the same, firstly to a flame located at C as diagrammatically shown in Fig. 1, so as to anneal the metal crushed by the previous stamping. and then to a cuttermember located at D and so shaped as to detach at a single strokethe bur 4 from the needles. Such cutter memand to facilitate the breaking of such porber comprises of course male and female dies so shaped as to correspond to the forms of the heads 3' and of the burs 4 to be cut oil.

formed. However, in the case of a. machine I now in'use which cannot be transformed,

such cutter member may be mounted on a separate machine.

By means of such a cutter member, the

needles are separated and the burs are cut off directly, which does away with the work by hand required by the machines now in use, work which is both a long and costly one.

The carrying out of such a process requires, of course, for the purpose of facili by fins resulting from the stamping, said device comprising two vertical platesor matrlces each plate having a width equal to the diameter of the needle heads and having a groove at its upper side shaped so as to rethe other, theiradjacent. ends having a rounded SECtlOlTWlllCll corresponds to the shape of the end of the needle heads, and an H shaped punch or cutting instrument having recesses attwo opposite sides, the cheeks whereof are adapted to slide against the side faces of the said matrices whereas the central part of the said punch between said grooves is adapted to slide against the adjacent ends of the said matrices, the transverse section of said grooves corresponding to that of the matrices and to the shape of the needle heads, substantially as described and illustrated.

In testimony, that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
